ELID Grinding Technology of Nano-Material Cutting Tool

Abstract:

As ELID grinding technology is characterized by simpleness, practicality, low cost and so on, it is wildly used in ultra-precision sharpening, ultra-precision grinding, ultra-precision polishing and some other fields of difficult-to-cut material. ELID grinding technology was applied in the grinding of cutting tool in this paper, and the cutting tools with nano-grained cemented carbide, common cemented carbide, nanoY-TZP ceramics and some other materials were respectively grinded. Then, the surface quality of their anterior and posterior grinding horns and their edge radius were studied and compared with traditional grinding technology of cutting tool. The results show that the surface roughness and edge radius of nano-grained cemented carbide cutting tool are respectively Ra2nm and 0.3μm, the surface roughness and edge radius of common cemented carbide cutting tool are respectively Ra20nm and 1μm and the surface roughness and edge radius of nanoY-TZP ceramic cutting tool are respectively Ra60nm and 0.2μm after grinding by applying ELID grinding technology, which are far better than that from traditional grinding technology; this further proves that the adoption of ELID grinding technology in the grinding of cutting tool is feasible.
